Hi, I'm still not familiar with laziness and I'm trying to make a
function recursively walk arbitrary data structures to perform some
action on all strings. The non-lazy version is quite easy to do:
(use
'clojure.walk
'clojure.contrib.str-utils)
(defn recursive-string-walk [f form]
(walk #(if (string? %) (f %) (recursive-string-walk f %))
identity form))
But it blow up the stack quite rapidly, I've tried to inject some
laziness inside, but only came up with a slight improvement. It can
take forms that are a little more than two time as deep.
(defn recursive-string-walk [f form]
(walk #(cond
(string? %) (f %)
(seq? %) (lazy-seq (recursive-string-walk f %))
:default (recursive-string-walk f %))
identity form))
Is there a way too make a fully lazy version of this function?
Thanks
